Caleffi 1/2″ Series 309 Pressure & Temperature Relief Valve Set at 90°C 7 Bar
The Altecnic 309 temperature and pressure relief valves are used to control and limit the temperature and pressure of hot water contained in a domestic storage cylinder, preventing the water from reaching 100°C. When the set conditions are reached, the valve discharges a sufficient amount of water to allow the temperature or pressure to return within the system’s operating limits. The valves have been designed for use on unvented hot water systems.
